摘要：
In accordance with one embodiment of the present disclosure, a method of evaluating the operating characteristics of a DBR laser diode is provided. According to the method, a diagnostic electrical current (II)is injected into the wavelength tuning section of the DBR laser to generate amplified spontaneous emission (ASE) of light in the wavelength tuning section. Light emitted from the wavelength tuning section is absorbed by the gain section and photo current (ISAIN) generated by the light absorbed in the gain section is measured. The photo current (ISAIN) measured in the gain section can be correlated with an evaluation of the operating characteristics of the DBR laser diode. For example, the measured photo current (ISAIN) can be correlated with a substandard operating characteristic when it departs from a given photo current metric by more than an acceptable amount. Alternatively, the measured photo current (ISAIN) can be correlated with a certified operating characteristic when it departs from the given photo current metric by an acceptable amount. Additional embodiments are disclosed and claimed.
摘要（中）：
根据本公开的一个实施例，提供了一种评估DBR激光二极管的工作特性的方法。 根据该方法，将诊断电流（II）注入到DBR激光器的波长调谐部分中，以在波长调谐部分中产生放大的自发发光（ASE）。 从波长调谐部发出的光被增益部吸收，并且测量由增益部吸收的光产生的光电流（ISAIN）。 在增益部分中测量的光电流（ISAIN）可以与对DBR激光二极管的工作特性的评估相关。 例如，当测量的光电流（ISAIN）从给定的光电流度量偏离超过可接受的量时，其可以与不合标准的工作特性相关。 或者，当其测量的光电流（ISAIN）当其从给定的光电流度量偏离可接受的量时，可以与经认证的操作特性相关联。 公开并要求保护附加实施例。
